Define the 3 signals for activation and the 3 outcomes of the complement system.\
sp2606 [1]
* More than 40 proteins and glycoproteins involved in the complement system are synthesized by the liver, macrophages, epithelial cells, they are present in the blood in plasmatic form, membrane, some have an enzymatic activity, regulator or membrane receptorThese are elements of the humoral innate immune response, they fight infections, purify immune complexes and apoptotic bodies.
<span>There are indeed three ways to activate the complement:</span>
Classical pathway: Activated by Immunoglobulins in immune complexes, aggregated Immunoglobulins, DNA, CRP, apoptotic bodies .......it involves nine fractions, starting with C1, then C4, C2, C3, to form a classical C5 convertase, then, activation of C5, C6, C7, C8, C9.

Alternative pathway: activated by polysaccharides (bacterial endotoxin), vascular wall poor in sialic acid, aggregated IgE ...C3b like is the first component in the alternate channel cascade, it will create an amplification loop, and form an alternative C5 convertase.

Lecithin pathway: Activated by mannose, fucose (carbohydrate of microorganisms)The first component is the complex MBL / MASP1 / MASP2: "mannose-binding protein": works according to the same principle as the complex C1 of the classical way (MASP2 cleaves the C4 and the rest of the cascade is equivalent to that of the classical way).

the three ways have the same outcome: A C5 convertase (formed by one of the pathways) cleaves C5 into C5a and C5b: C5b is deposited far from other fractions on the antigenic surface. The fixation of C5b in the cell is followed by that of C6, C7, C8, and C9 (9 molecules of C9): formation of the membrane attack complex (MAC) ==> Death of the cell by osmotic shock

Which of the following chemical reactions proves the fact that the products of photosynthesis are reactants of respiration?
AlladinOne [14]
<span>The answer is:
Photosynthesis: 6 CO</span>₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP<span>

Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (</span>C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (<span>O₂)</span><span>. </span>

How does the primary transcript in the nucleus of a prokaryotic cell compare to the functional mrna?
aleksley [76]

Answer:

None of the answers is correct, because prokaryotic cell doesn't have nucleus

Explanation:

In eukaryotic cell, primary transcript is RNA synthesized via transcription in the nucleus. After processing it becomes mature mRNA. The processes of processining are addition of the 5' cap, 3'-polyadenylation, and alternative splicing (excision of introns). Because during the processing of RNA introns are removed the primary transcript is larger than the mRNA.
